DistroWatch.com: Put the fun back into computing. Use Linux, BSD.: "The bewildering choice and the ever increasing number of Linux distributions can be confusing for those who are new to Linux. This is why this page was created. It lists 10 Linux distributions (plus an honourable mention of FreeBSD, by far the most popular of all of the BSDs), which are generally considered as most widely-used by Linux users around the world. There are no figures to back it up and there are many other distributions that might suit your particular purpose better, but as a general rule, all of these are popular and have very active forums or mailing lists where you can ask questions if you get stuck. Ubuntu, Linux Mint and PCLinuxOS are considered the easiest for new users who want to get productive in Linux as soon as possible without having to master all its complexities. On the other end of the spectrum, Slackware Linux, Arch Linux and FreeBSD are more advanced distributions that require plenty of learning before they can be used effectively. openSUSE, Fedora, Debian GNU/Linux and Mageia can be classified as good "middle-road" distributions. CentOS is an enterprise distribution, suitable for those who prefer stability, reliability and long-term support over cutting-edge features and software."
